Title: Method of coating inner side of pipe with graphite
Inventor: SHIMADA YOSHIO
IPC: G21C21/00
Filed: 1978-04-05
Abstract: PURPOSE: In the formation of coating films using a coating dispersion containing a specific amount of graphite, the plunger is changed in outer diameter, thus controlling the film thickness of the graphite coating on the inner surface of tubes for covering fuel rods of nuclear reactor.  
     CONSTITUTION: Into the inside of pipe 4 to be coated are placed coating 9 prepared by dispersing 20W30 wt.% of finely powdered graphite in a volatile organic solvent as isopropyl alcohol along with plunger 8. The outer diameter of plunger 8 is made slightly smaller than the inner diameter of pipe 4 to be coated. The coating dispersion in the gap between plunger 8 and pipe 4 forms thin layers and aheres to the inside surface of the pipe 4. Plunger 8 is moved and coating film of graphite is formed on the inner surface of pipe 4 in uniform thickness. The thickness of the graphite film depends on the content of graphite in coating dispersion, kinds of dispersants of volatile organic solvents and the diameter of plunger 8.

Title: Oscillation-proof stage
Inventor: HAMAGUCHI SHINICHI
IPC: B23Q15/007
Filed: 1989-02-22
Abstract: PURPOSE:To decrease oscillations of the whole structure of an oscillation-proof stage even though its oscillations are caused by migration of the center of gravity in a device having a movement part by causing a holding part to be equipped with a cushioning part and further, providing in advance a means of pressure compensation for the cushioning part so as to cope with migration of the center of gravity. CONSTITUTION:A control signal C is sent from a control device 10 to a hydraulic mechanism 11 so that a pressure is applied to the cushioning part 2 of an oscillation proof stage. Then the movement of a piston 12 is controlled by controlling the oil pressure of the hydraulic mechanism 11. The gas pressure in a pressure chamber 13 to which a gas is fed through a piping 8 is adjusted and a prescribed gas pressure is given to the cushioning part 2 in response to the gas pressure adjusted in the pressure chamber. Further, the pressure in the pressure chamber 13 is sent back to the control device 10 as a feedback signal F through a pressure gauge 14. It may be as well, therefore, to compensate the gas pressure again according to a result of the feedback signal. Oscillation factors, e.g. the movement of the stage and the like accompanying the movement of a movement part that can be measured in advance are removed surely and then highly accurate positioning of the movement part is thus performed.

Title: Matrix liquid crystal panel
Inventor: HANDA SHIYUNJI
IPC: G02F1/13
Filed: 1978-04-06
Abstract: PURPOSE: To simplify the electric heating pattern as well as to increase the display density without lowering the display contrast by forming more than one matrix block in the same liquid crystal panel.  
     CONSTITUTION: In the 3-step matrix with one display line divided into M parts, the vertical line is the display electrode and one line is separated into three blocks with the lead wire led out from each block. Horizontal lines X 1  W X 4 are the scanning electrodes with same scanning signals applied to same numbers and to be  opposed to each block of the display electrode by one line. Accordingly, the driving  duty becomes 3/n (3/12) in case the number of the full scanning line is set to n  (n = 12). As a result, the number of the lead wire running between picture elements can be decreased with the simplified pattern structure as well. At the same time, the density of the picture element is increased although the size of the picture element is same, and the display quality is enhanced with the advantage secured for miniaturization of the panel.

Title: Protection circuit of switching element
Inventor: NAKAI MASAKI
IPC: H03K17/16
Filed: 1984-03-02
Abstract: PURPOSE:To protect a switching element by providing a switching suppression circuit detecting the switching delay of one switching element and inhibiting both the switching elements from being conductive at the same time. CONSTITUTION:When a transistor (TR) 10 or 12 is conductive, since TRs 28, 30 of the switching suppression circuit 26A or 26B are conductive and the TR4 or 8 is nonconductive, it is necessary to make the TRs 10, 12 nonconductive at all times in order to make the TRs 4, 8 conductive. That is, even if the base of the TR10 or 12 transits to a high level, while the TRs 10, 2 or the TRs 12, 6 are not transited to the nonconductive state, the TR4 or 8 is not conductive. Thus, the flowing of the short-circuit current because of the simultaneous conduction of the TRs 2, 4 or the TRs 6, 8 is prevented, destruction of the TRs 2, 4, 6, 8 is prevented and the reliability of operation is improved.

Title: Voyage information display device
Inventor: YUI KATSUO
IPC: G01S7/22
Filed: 1989-02-21
Abstract: PURPOSE:To display an image plane of desired voyage information in the shortest time by setting a contraction scale and an image plane center position automatically and specifying an image plane center with a graphic cursor. CONSTITUTION:When voyage information is displayed for a 1st time, the voyage information is inputted from a voyage information storage device 1 to a voyage information range arithmetic unit 6 to calculate the image plane center position and contraction scale for displaying the voyage information as one image plane. Then an image plane information arithmetic unit 4 calculates image plane information by using the image lane center and contraction scale and outputs them to a display device 5. When the image plane center position is changed, a graphic cursor position input device 3 moves the cursor to a desired image plane center by viewing. Further, when a desired contraction scale is inputted by an image plane specification input device 2, the arithmetic unit 4 converts the position of the cursor into the longitude and latitude of the image plane center to calculate and output the image plane information to the display device 5. Consequently, only single-time arithmetic and display at the time of a change in contraction scale are required and the image plane of the desired voyage information is obtained in the shortest time.

Abstract: PURPOSE:To increase the light recovering efficiency and to prolong the life, by passing a strain toroidal compound that has absorbed solar energy through piereced passages in a catalyst having a honeycomb structure and allowing the  generated heat of the isomerized reaction to be absorbed into a fluid flowing through other pierced passages in said catalyst. CONSTITUTION:A compound such as rhodium compounds and nickel compounds, especially the complex materials, is supported on an organic material such as polystyrenes or an inorganic material such as zeolite, and is formed into a honeycomb structure to produce the honeycomb catalyst O. The energy convertor 2 that will be isomerized by sunlight such as quadricyclane-norbornadiene is isomerized by sunlight, and is passed through the pierced passages in the honeycomb catalyst O. Thus the energy convertor 2 comes in contact with the catalyst to be isomerized and therefore heat is generated, which is transferred to the heat energy absorbing fluid 1 passing through other pierced passages in the honeycomb structure. Accordingly, the heat recovering efficiency can be increased.
